Title: Improvements in devices for absorbing moisture in containers
IPC: B65D51/30
Filed: 1923-12-31
Abstract: 229,054. Moyer, P. S. Dec. 31, 1923. Internal fittings.-Relates to moisture-absorbing devices formed with or attached to the closures of containers for food, confectionery, &c. According to the invention, the device is operable to admit air to a hygroscopic substance when the closure is on the container, and to prevent the access of air when the closure is removed. In the form shown in Fig. 1, the cap 8 is formed with interrupted screw-threads to engage with threads on the mouth of the container, a washer 9a forming an airtight fitting when the cap is screwed home. A hygroscopic pad 10 is mounted in a casing 11 with a perforated bottom 12. A cover-plate 15, also perforated at 17, is mounted to rotate about a bolt 13 which secures the whole device to the closure. When the closure is on the container, the cover-plate is rotated by a handle 19 so that the perforations in the bottom 12 and plate 15 register, and the pad 10 is operative. When the closure is removed from the container, the cover 15 is rotated to close the perforations. In a modification, the cover-plate resiliently engages the inside of the container mouth so that the act of applying or removing the lid uncovers or covers the perforations as required by relative rotation of the parts 12, 15. In another form, the casing 11 is resiliently pressed against a cover-plate until the closure is applied, causing a disengagement against the action of a spring. In this form, the sides of the casing may also be perforated and the cover-plate be arranged to open and close these perforations.

Abstract: 632,582. Projectile fastening device and gun therefor. TEMPLE VELOCITY EQUIPMENT, Inc. Nov. 7, 1946, No. 33117. Convention date, Aug. 15, 1944. [Classes 9 (i), 92 (ii) and 119] A hand-operated explosively-actuated device for securing a time-bomb to a ship below the water-line comprises a bracket from which the bomb may be suspended, one wall of the bracket being adapted for juxtaposition with the side of the ship and having an opening in alignment with a piercing stud or projectile 27 in a gun-like barrel 7 supported in a socket in the bracket. Furthermore, explosive means behind the stud when discharged drive the stud forward into the bracket opening and the ship's side to secure the bracket. The metal bracket 1 is mounted on a metal plate 2 secured to a time-bomb 4. Slidably mounted in a socket in the bracket 1, the barrel 7 is held in position by a spring-pressed ball 8 projecting into a peripheral groove 11. The bracket has a central opening 13 in alignment with the muzzle of the barrel 7. A sealing disc 16 may be soldered to the front of the barrel. A cap 17 screwed on to the rear end of the barrel presses against the barrel the flanged outer end of a cartridge 18, which is the same as that in U.S.A. Specification 2,064,503, and contains an explosive charge 21 and detonator 22. The cartridge wall is weakened by a peripheral groove 23 and the front end of the cartridge has a boss 24 engaging in a recess 26 in the enlarged base of the stud 27. Projecting rearwardly from the cap 17 is a yoke 30 in which is slidably mounted a spring-pressed firing-pin 31. The point of the pin 31 projects into a slot 33 in a trigger block 34. On removal of a safety key 36, Fig. 3, by means of a ring 38, the trigger block 34 can be removed by a firing-ring 37, whereupon the firing-pin is urged forward by its spring 32 to initiate the detonator 22. The pressure inside the cartridge builds up until rupture occurs at the groove 23, whereupon the front portion of the cartridge drives the stud 27 forward to lodge in a structure 12 in front of the bracket, the enlarged base of the stud being arrested by the bracket. The recoil from the explosion overcomes the resistance of the ball 8 and drives the barrel backwards out of the socket. The stud 27 has a knurled body to prevent rotation in the structure 12. A modified form of stud for use in penetrating metal structures is described.

Abstract: 794,108. Fluid-pressure servomotor-control systems. SAMSON APPARATEBAU-AKT.- GES. Nov. 16, 1954 [Nov. 16, 1953], No. 33210/54. Class 135. In a fluid-pressure servomotor control system of the kind having a pressure-sensitive device, for example, a bellows 1, Fig. 1, subjected to a control pressure in a pipe 3 to control a leak-off valve 7 in a line 10 supplying compressed air to operate a valve motor, which may be a diaphragm 11, piston or bellows to position a valve member 17 to control the flow of a pressure fluid through a valve 14 in accordance with the control pressure, the usual helical spring 23 connecting the valve operating spindle to the pressure-sensitive device is replaced by a torsion rod. As shown in Fig. 2, a torsion rod 35 mounted at one end in a bearing 36 and secured at its other end in a bush 37 rotatable in a housing extension 34, is fixed to an arm 38 on which the upper plate 26 of the pressure-sensitive device is mounted and adjustably secured to a lever 40 which, through a stud and slot connection 45, 47, an angle bar 44, and clips 43, is connected to the valve operating spindle 24. Thus the angular position of the lever 40 with respect to the rod 35 may be adjusted and also the distance between the axes of the rod 35 and the operating spindle 24. On, for example, an increase in control pressure the plate 26 moves upwardly to decrease the opening of the leak-off valve and hence increase the pressure acting on the valve motor to move the spindle 24 downwardly to decrease the opening of the valve attached thereto to correspond to the increased control pressure. On, e.g., upward movement of the valve spindle 24, consequent upon an increase in the pressure of the controlled fluid, the opening of the leak-off valve will be reduced so that the pressure acting on the valve motor is increased to re-adjust the position of the valve member in accordance with the control pressure.
